Application led March 31, 1927. Serial No. 179,884.

This invention relates to the blade-holding body and handle of a safety-razor, the bodyeincluding a guard plate and a cla-mping plate adapted to operatively confine a normally flat resilient blade, such as the Gillette, andfimpart a transverse curvature 'to the blade when they are adjusted to clamp the latter. v

One Object of the invention-r is to provide an improved construction of the guard and clamping plates, whereby they may be quickly and conveniently assembled and separated vwithout the employment of screw threads, the v construction being such that the said plates and the means for clamping them on the blade may be composed entirely of two sheet metal parts, and manufactured at a minimum cost, no cutting work being involved.

Another object is to provide a .folding razor Or blade-holding body including a handle composed also of two sheet metal parts, made entirely without lathe and screw-cutting work, able against the body ofthe razor, and forming an operative angular handle projecting from the body when adjusted for use, the being slidably and Of the accompanying drawings forming a part 0f this specification,'-

a section on line 3--3 of Fig` 15 and 16 On the guard plate,

showin the parts in the 'relative positions cated by 12 designates a transversely curved guard plate of sheet metal,

having guards at its opposite longitudinal edge.portions,spreferably formed by cutting lather-conducting slots; 13, the slots being separated by narrow bars 14, -constituting the equivalent of the usual comb teeth with which a guard plate is provided.

The guard plate is provided at its opposite ends with holding-down coupling members, adapted to hold down' the clamping plate hereinafter described, and preferably formed by upstanding ears 15 and 16, integral with the plate. Each ear includes a neck portion 160 and shoulders 17 overhanging the ends of thev neck portion. Theguard plate and its integral coupling'members constitute a single piece of sheet metal.

The guard plateforme a seat adapted to support a flattened'resilient blade 18 of the Gillette type, with its cutting edges raised above the seat,- as shown by Figure 4. 19

designates a transversely curved clamping the shoulders 17, as shown by Figure 4.

When-the clamping plate is thus deposited on the blade, it is in the inoperative position shown by blade against the guard plate, as shown by The clamping plate is provided with complemental coupling members engageable with the holding-down membersl by an'endwise movement of the clamping plate to the operative position shown by Figure 1. One of said. coupling kmembers' is preferably ein-4 bodied in an angular orifice 20, in one end portion of the clamping plate, including a by Figure 8, and a narrower portion 22, the ends of which are adapted to be moved under the shoulders of the member 16, as indi- Figure 1. The other of said coupling members is preferably embodied in open recess 23, vhaving inclined ends 24. When 'the clamping plate is in the position shown by Figure 8, the recess ends 24 are adapted to be moved underth'e shoulders of the'holding-down member 15, as indicated by Figure 1. `The coupling members on the clamping plate are integral parts thereof,

so that the clamping plate and its coupling Figure 8, and is movable sidewise from said position to curve the clamping plate is de-.` .posite'd thereon, said plate is elevated above said orice wider portion 21,' formedV to receive the holding-down member 16, as shown members are composed of a single piece of sheet metal.

ln assembling the parts, the dat blade is first deposited on the guard plate and is positioned thereon by sheet metal ears or studs 26, integral with and struck up from the guard plate and formed to enter the usual orifices 27 (Figures 1 and 2) in the blade. The clamping plate 19 is then deposited in the position shown by Figure 8, on the flattened blade, and is supported by the latter above the shoulders 17, as shown by Figure 4. The operator next presses the clamping plate sidewise inwardly, to curve the blade against the guard plate, andthen moves the clamping plate cndwise to the position shown by Figure 1, thus engaging the ends 22 o'f the orifice 20, with the overhanging shoulders of the holding-down member 16, and the ends 2-1 of the recess 23, with the overhanging shoulders of the holding-down member 15, so that the blade is operatively clamped between the guard plate and the clamping plate, the blade being tensioned, so that in its efiort'toy assume its normal form, it exerts suilicient frictional pressure on the clamping plate to prevent accidental movement or' the latter to the blade-releasing position shown by Figure 8. Such movement may be easily caused by pressure of the operators finger or thumb on a roughened portion 30 of the clamping plate, inl

the direction of arrow The clamping longitudinal slots and permittingthe described endwise movements of the clamping plate.

l provide the razor body with a handle composed of two members 32 and 33, pret'- erably of sheet metal and formed as shown by Figures 6 and .7. Said members are hingedl at their inner ends to the opposite ends of the guard plate, preferably by sheet metal hinge sockets formed by bent ears 34rintegral with the guard plate and projecting inwardly therefrom., and sheet metal hinge pintl'es or trunnions 35, integral with the handle members and engaged with said sockets to turn therein. f

The handle members are providedy with adjustable connecting means between their inner and outer ends, permitting the folding of the members as indicated by dotted lines in Figure 2, and their movement from the folded positions to form an Iangular handle, projecting from the uard plate, as shown by full lines, the handle members and the guard plate forming an angular openfore finger may be inserted, the inner sides of the members, and second linger bearing at the on the outer sides of the mem- X in Figure 1. plate 19 is provided with to bear on the thumb same time, bers.

rlhe said adjustable connecting means, in this instance, is provided bythe edges ol the slot.`

31, receiving the: studs 2G v alongitudinal slot 36, formed in the member 32, and a T-shaped outer end portion 37, formed on the member 33 and slidable in The end portion 37 is bent from the plane of the member 33, and 4extends through the slot. rlhe outer end 38`of the slot constitutes a stop, limiting theoutward sliding movement of the end portion 37, and preventing the separation of the handle members from each other, when said members are hinged to the guard plate. ln practice the member 33 will be folded closely against the guard plate, and the member 32 will be folded closely against the member 33. The dotted line representation in F igure 2 is intended to show the handle members incompletely folded. rlhe IiP-shaped end portion 37 is continuously edges oi' the slot 36, so that itis slidably and inseparably engaged with the member 32. l ry The drawings show the parts enlarged to about twice their actual size.. When the razor is folded, it is extremely compact and may be carried in a vest pocket, or hung on a watch chain, by a split ring engaged With a. notch 40, in one edge of the orice 20.

l claim:
